Abstract
The invention discloses a damper end cover assembly which comprises a guider and an end cover. The end cover is a cylindrical hollow cover, at least three barbs are arranged on the end cover, the barbs are distributed along the peripheral direction of the end cover, one end of each barb is connected with the end cover, the other end of each barb extends into the end cover along the peripheral radial direction of the end cover, a plurality of grooves are arranged on the guider along the peripheral direction, and the positions and the number of the grooves correspond to the positions and the number of the barbs on the end cover. The barbs are arranged on the end cover, the barbs are pressed into the guider to hook the guider, the end cover is connected with the guider, then a damper oil cylinder is arranged, and accordingly the end cover assembly is convenient to assemble and disassemble. When the assembly is installed, a spring is in a compressed state, and a sealing ring can be directly installed at the sealing portion. When a spiral sleeve is screwed up, the sealing ring cannot move in the radial direction, and assembling sealing performance of the damper is guaranteed.
Description
Technical field
The present invention relates to a kind of vibration damper accessory, the end cover of shock absorber assembly that especially a kind of easy accessibility, fitting tight performance are good.
Background technique
Existing gas-filled type adjustable shock absorber end-cap assembly is Spielpassung for the ease of dismounting end cap cylindrical and shock absorber oil cylinder internal diameter, owing to being equipped with spring between end cap and guider, need during assembling to be screwed by swivel nut and oily cylinder cylindrical to make backing plate the part such as seal ring, end cap is pressed into oil cylinder downwards; When the part such as swivel nut, end cap, guider, spring, seal ring, backing plate of vibration damper loads oily cylinder successively, because spring is in the state of flicking, and end cap step place is higher than oily nozzle portion, when swivel nut screws off, seal ring easily produces radial-play, cause seal ring to be sheared by oily nozzle and backing plate and be damaged, destroy the sealability of seal ring.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of easy accessibility, the end cover of shock absorber assembly that fitting tight performance is good.
For solving the problems of the technologies described above, present invention employs a kind of end cover of shock absorber assembly, comprise guider and end cap, described end cap is cylindrical, hollow lid, end cap is provided with at least three barbs, described barb distribution is at end cap circumferencial direction, and described barb one end is connected with end cap, and the other end stretches in end cap along end cap circumference radial direction; Described guider is along the circumferential direction provided with multiple groove, and position and the quantity of described groove and barb on end cap are corresponding.
The quantity of described barb and groove is three, and barb and groove are evenly arranged on end cap and guider respectively.
The beneficial effect that the present invention has: this end-cap assembly by arranging barb on end cap, during installation, hook guider after first barb being pressed into guider by the groove on guider, end cap and guider are linked together, then load shock absorber oil cylinder, make end-cap assembly easy accessibility; Because the spring in this assembly is in compressive state, seal ring directly can load sealing position, and when swivel nut screws, seal ring can not produce radial-play, thus ensures vibration damper fitting tight performance.

Embodiment
As shown in Figures 1 to 4, for a kind of end cover of shock absorber assembly, comprise guider 3 and end cap 1, end cap 1 is cylindrical, hollow lid, end cap 1 is provided with at least three barbs 2, barb 2 is distributed in end cap 1 circumferencial direction, and barb 1 one end is connected with end cap 1, and the other end stretches in end cap 1 along end cap 1 circumference radial direction; Guider 3 is along the circumferential direction provided with multiple groove 4, wherein the position of groove 4 and barb 2 on end cap 1 and quantity corresponding.
As shown in figs. 1 and 3, end cap 1 is along the circumferential direction evenly provided with three barbs 2, accordingly, guider 3 is along the circumferential direction evenly provided with the groove 4. of three sizes slightly larger than barb size
As shown in Figure 4, during the assembling of this end-cap assembly, first spring 8 is arranged in end cap 1, then guider groove 4 is aimed at end cap barb 2, by guider 3 holddown spring 8, make guider 3 be pressed in end cap 1, then guider 3 is rotated 15 °, now the barb 2 of end cap 1 is hooked on guider 3, and therefore guider 3 and end cap 1 can not be flicked by spring 8, makes guider 3 and end cap 1 be linked to be an entirety.
As shown in Figures 4 and 5, during assembling vibration damper, can first the parts such as guider 3, spring 8, end cap 1 be dressed up as integrated end cap assemblies, then this assembly is loaded shock absorber oil cylinder 9, because now spring 8 is in compressive state, end cap 1 step place is lower than 9 mouthfuls, oily cylinder, seal ring 7 directly can put into sealing position, and when swivel nut 5 screws with oily cylinder 9, seal ring 7 can not produce radial-play, avoid seal ring 7 sheared by 9 mouthfuls, oily cylinder and backing plate 6 and be damaged, make seal ring 7 can reliable sealing.
The end cap 1 of this invention can be processed on the basis of existing end cap 10 structure, course of working is as follows: cut out on the side of existing end cap 10 three rectangular, then by rectangular to lateral buckling in existing end cap 10, finally on existing end cap 10 formed three hook 2, complete the processing of end cap 1.
